Quick Pickled Red Onions

Pro tips

• Slice onions as thin as possible (1/8 inch) so they absorb brine evenly and pickle faster.
• Heat the vinegar mixture before pouring over onions to speed up the pickling process and improve flavor absorption.
• Taste after 1.5 hours—they'll be tangy and still crisp; longer soaking softens texture, so adjust timing to preference.
• Store in glass jars or airtight containers with brine to keep onions submerged and prevent browning.

Substitutions

• white vinegar → apple cider vinegar or rice vinegar (adds fruity or mild sweetness)
• white sugar → honey or agave (adds depth, adjust to taste)
• MSG (optional) → fish sauce or soy sauce 1/2 tsp (adds umami without MSG)

Storage & make-ahead

Store in an airtight glass container submerged in brine for up to 1 week refrigerated.

How long do quick pickled onions stay crisp?

They're crispest within the first 24 hours but remain good for up to 1 week refrigerated in their brine.

Can I make this recipe without MSG?

Yes, MSG is optional. The pickles will still be flavorful; MSG just adds umami depth.

How do I slice red onions thin enough for quick pickling?

Use a mandoline slicer or sharp knife to cut onions into 1/8-inch slices so they pickle quickly and evenly.

Can I scale this recipe up for meal prep?

Yes, the ratios scale linearly. Double or triple the amounts for larger batches stored in mason jars.

What's the difference between quick pickling and traditional pickling?

Quick pickling uses heat and thin slices to pickle in hours rather than days, with no canning process needed.
